1 1/2 pounds yellow squash, cut into 1/4-inch-thick slices
1 1/2 pounds zucchini, cut into 1/4-inch-thick slices
1/4 cup butter, divided
2 cups diced sweet onion

Preheat the oven to 350°. Bring the first 2 ingredients and water to cover to a boil in a Dutch oven over medium-high heat, and boil 5 minutes or until crisp tender. Drain; gently press between paper towels.
